What is a tsunami simulation? A tsunami simulation is the creation of an artificial tsunami based upon knowledge of the physics of how tsunamis are generated and how they behave converted into mathematical formulae that can be programmed and run on a computer. A particular simulation requires: • • A particular tsunami source Appropriately gridded bathymetric data Appropriately gridded coastal topographic data Tidal components
Why do we need tsunami simulations? 1. Hazard Assessment • Historical data are too limited. • Given what is known about potential tsunami sources and their recurrrence rates, what is the likelihood of being impacted by a tsunami of a particular size and effect? 2. Tsunami Forecasting • Accurate forecasting of tsunami impacts during a tsunami event. 3. Tsunami Scenarios • Education about what would happen for any particular tsunami situation
Why can be learned from tsunami simulations? 1. How long after generation will the tsunami arrive? 2. When will be the biggest wave? 3. How long will the hazard last? 4. How many places will be affected by the tsunami? 5. Which places will be affected most? 6. What areas will be inundated and how deep? 7. What currents will be experienced?
